In a documentary set to air tonight called Apple’s Broken Promises, BBC One went undercover at Pegatron, one of Apple’s main supply chain partners in China. The findings from inside Pegatron’s walls show that “Apple’s promises to protect workers were routinely broken,” according to the report.

Another alarming revelation was that Apple could be using tin dug by impoverished children in illegal Indonesian mines. Apple is denying the allegations, but BBC One is committed to unearthing a sensitive topic the iPhone maker has spent years trying to put to rest.

The official BBC One Twitter account had a surprise for fans of its hit show Sherlock Wednesday with a tease that the oft-delayed series about a modern Sherlock Holmes and his faithful sidekick John Watson will be returning.

"Miss me?" #Sherlock, the hit @BBCOne drama, will return for a Special, followed by a series of three new episodes. #221back
